Calibrate Compass turned RED

My compass was not accurate, so I started a calibration routine. After turning it several times as instructed, it turn red instead of the green that I was told to expect. What's wrong? Any tried that before?

Had he same problem. Fixed it by being at least 6 feet away from other electronics and by calibrating the phone on a flat surface to make the twisting and turning as even as possible. Calibrated right away. Hopefully that helps.

The only way i could get mine to calibrate, was to wipe back to factory. It would only calibrate with the keyboard closed, couldn't get it to calibrate with the keyboard extended. It will only calibrate once, if you try to calibrate it twice, it will only turn red.
An extensive three way conversation with a Verizon tech and a Motorola tech was useless. Dont know if this is a bug in the software or what, in my opinion the unit is defective.
You"ll need to wipe the device then, before you sync or install any apps, calibrate the compass.
